“…Planar photonic crystal structures with various combinations of their constituent layers have attracted close attention of researchers due to their capabilities for effective control of optical radiation [1][2][3][4][5]. Control of reflection and transmission spectra for such structures, as a rule, is achieved by including layers in their composition, the material parameters of which depend on easily variable external factors (electric and magnetic fields, angle of incidence and polarization of incident radiation) [6][7][8][9][10].…”

The transformation of the transmission spectra of linearly polarized radiation passing through a symmetric photonic cell is studied based on numerical analysis. The cell consists of two layers of magnetic semiconductor with a graphene monolayer on each and a central dielectric layer located between the graphene monolayers. It is possible to achieve amplification in the near terahertz range in graphene layers due to charge carrier drift. Control of transmission spectra and polarization of transmitted radiation can be achieved by changing the Fermi energy of graphene layers, by changing the external magnetic field, and by changing the thickness of the dielectric layer and the orientation of the incident radiation polarization plane.
